The American Analyst describes q very
ingenious computing scale, the invention
Of Mr.. l.. A. Meneger, of Lansing, Kan.
The scale consists of a simple balance
arm resting on nickel point supported by
standard about eighteen inches high.
There are two scales on the taiance arm.
One denotes the weight and total cost of
the article weighed; the other the unit of
price, which is designated by q shGin q
weight. From this sliding weight Is sus-
pended the scoop or slab to Contain the
article to be weighed. By this scale the
total cost of any article to be weighed is
given. For instance, if seven and a half
pounds Of butter re placed on the scale,
snd the price be 13d cents 8 pound, the
scale shows at once that tne total cost is
Sl.014. Or if purchaser wish 16 cents
worth Of tea, the price of which was IS
cents pound, the weight would be fixed,
the sliding one at 70 cents, the other one
at the l6 cents mark on the computing
scale. Then, when enough tea should
have been put into the scoop TO cause the
scale to balance, that quantity would
be the l6 cents worth desired.
The stories once so current, thst seeds
taken from ancient Egyptian tombs have
grown are believed, if not demOnstrabIy
false, TO lack the guarantees Of truth that
tales of the kind should require; and
nothing as to the vitality of seeds can be
built upon them. But DR.. LindIey tells
OF raspberries that were raised il the gar
dens OF the Horticultural Society from
seed taken from the stomach of man who
was buried IN barrow near the time of
the Emperor Hadriau; and Professor
Duchartre and others tell of seeds whose
identity is properly youched for, taken
from under the foundations OF an old
sAease IN Paris, probably from the original
soil of the island, and, therefore, cOevgl
with the city, which terminated and
proved to be seeds of JunCus bufOniuS,
an indigenous plant of that soil.
Some of the features of shorthand
writing. synChrOnOus-multipleX tele-
graphy and tYpe-writing are combined in
system of stenO-telegraphy invented by
NJ. G. A. Cassagnes, of Paris. In recent
experiments over wire running from
Paris 10 Orleans and OsCk, messages were
sent at the rate of over 200 words
minute, that being the highest speed at
tainGble by a uimoIe-h1geTed operator.
By means Of an automatic transmitting
apparatus, using a strip OF paper pre-
viously perforated, as in some of the
systems Of telegraphy already in vogue,
IL, 900 words per hour were sent over 3
line $50 kilOmeters in length, the messages
being automatically printed by the receiV-
ing instrument Science.
For green transparent varnish for
metals, grind small quantity CT Chinese
blue with double the quantity of finely
powdered chromate of potash ct requires
the most elaborate grinding; add 8 suhi-
cient quantity of cOpaI vsrnish thinned
with turpentine. The tone may be altered
by adding more or less of one or the other
of the ingredients.
Owing to the increased electrical inten-
sity of the atmosphere, which is induced
by the continual evulsion Of steam and
smoke, DIR. Andres estimates that the
danger from lightning is from three TO
five times greater than it was fifty years
ago.
